I have a 2000 Pontiac Grand Am SE sedan (base model) with a 3.4L engine at 142Kmi that was just diagnosed with an intake manifold coolant leak by an independent shop.
I've done some googling and found that this is a known problem with this engine (including a class action suit). So far the leak is just external; no coolant in the oil and no oil in the coolant.
Leaking intake manifold gaskets on General Motors 3.1L V6 engines? Mine is a 1998 Grand Am with low milage (40K) and I have been told I need to spend $900 to replace the intake manifold gasket because it is leaking antifreeze into the engine oil.
View 8 RepliesWell, I decided to take on the dreaded task of replacing the lower manifold intake gaskets and put in new isolator bolts. It was a major undertaking, and when I finally finished the oil change and fired up the car, it sounded fine. Then I checked under the hood.
I saw coolant spurting out the side of one of the hose connections that I had to take off and put back on. I thought the gasket on it looked pretty worn, but wasn't expecting this!
Unfortunately I don't know the name of the hose connection to pick up a gasket at the store ... it's the larger lower hose that is bolted on to the lower intake, not the hose slightly above it that has the plastic clips.
What is the name of this hose connection so I can try and find one at the store? It's a 2003 Windstar model.
I have a 2006 F150 screw 4.6 auto 116k miles that has evidence of a small coolant leak where the intake manifold joins the head. This is on the drivers side directly under the thermostat housing. The t-stat housing is dry and the hoses all appear dry. It's just wet right at the gasket where the manifold joins the head. Reservoir is still normal so it's not leaking too much just yet.
I searched this site and youtube but didn't find any other posts. Lots of problems with older trucks with composite manifolds but nothing for this one. It looks like a part of the bottom of the manifold is plastic but the entire top and where it is leaking is all aluminum.
It seems odd that this would start in the winter time just driving back and forth to work (no load). And, yes the antifreeze is good. Just wondering if this is a known issue with this truck. Is it just a matter of replacing the gaskets or is there some other flaw I should be concerned about?
So I recently bought a 2002 volvo s60 base sedan with a dead instrument cluster. I sent it out to be repaired and when I got it back and plugged it in, it did not work. At first I thought it was the company who repaired who messed up, but I looked up the numbers on the cluster and it is out of a 2001 Volvo. I have no way of contacting the previous owner to find out if they tried swapping out the cluster with one from the junkyard, or if they have the original cluster.
I don't know what to do because I cant send the cluster back to the company since I don't know if its the original one or not. Is there any way I can find out what the original numbers are on my cluster. Is there any way to find out the original numbers on the cluster using my vin number? I called the volvo dealer and all they gave me was the part number for a new cluster.
If you have a coolant leak at the y hose for the intake manifold and the thermostat, make sure you replace the upper radiator hose as well as the y hose.
View 3 RepliesCoolant spilled on my upper intake manifold. I washed it off to the best of my ability but when i started the car white smoke came from tge exhaust. What my next move should be?
View 3 RepliesI have a 1999 Ford Expedition. A couple of days ago The engine started losing coolant as soon as the engine cooled. I replaced the coolant only to lose it again when the engine cooled. I was told that it is more likely the intake manifold gaskets leaking. It seems they are right. What is the cost to repair if I take it to a mechanic?
View 1 RepliesI just got a 2000 Passat 1.8T with a bad motor.
Symptoms include: rough idle, oil leakage, coolant light comes on after running for about 2-3 min., I checked the coolant res. and it has what I suspect is oil in it. I know that the PO ran cheep oil and oil filters the last 2 oil changes and this has caused the famous cannibalization of the engine but what I need to know is would this feed oil into the the coolant over flow tank? There also seems to be some oil/coolant seeping from the upper left.
The car only has about 90k on it and most of those are highway miles, other than cheep oil, the car has been very well taken care of.
My check engine light came on and I had it checked at Advanced Auto and it said it had to do with my air intake so I checked if it was leaking and the hose closest to the engine has a big rip in it so I taped it for now.

I have a 2004 pontiac grand prix gt. I read some where that some of these have the resistor and blower motor close together and that the molding or rubber that runs at the bottom of the windshield after time will leak water into the blower motor and resistor and cause a short. I believe this has been the cause of a lot of my issues with car shorting out. the other day had to have it towed for the first time in its 11 years and found out it was one of the j fuses arcing causing the car not to start.
It's already 267,000 miles.
Today I was on my way back home from a weekend trip to see family when the CEL came on. The car was running fine no problems (we had driven 200 miles). Gas mileage was good, good power, no weird noises, engine temp was fine (it was 100 degrees outside). But being how the car has 39k on it and its the most expensive thing I own; I pulled over and had autozone scan it for me. It came up as Intake Manifold Sensor. I have never worked on this car but Im going to at some point, I'll replace it myself if it isn't to hard. I am wondering if it is as simple as replacing the sensor or could there be an underlying issue like a blown intake manifold gasket (like i said the car was running fine though)?
View 6 RepliesTurned the key on my 2002 MC SS, V6, 3.8L, and the Intake Manifold exploded.
Intake Manifold Exploding on a GM V6, 3.8L? It sounded like a 12ga shotgun. Fortunately no one was looking into the engine compartment at the time as they likely would have been killed given the amount of shrapnel from this explosion. Note that the explosion was powerful enough to blow off the oil cap, which is screwed on with very thick threads.
The vehicle was at my mechanics at time and in his forty years he's not seen an intake manifold explode save for those residing on Top Fuel or Funny Cars.
One of the nozzles on the back of my intake manifold broke off. I don't know how to better explain it. The ones the back of the manifold closest to the firewall there are several hoses that hook to the manifold. The second one from the left broke.
View 7 RepliesI'm having a problem with the intake manifold shifter not working on my r32. I've tried all of the normal fixes, the shifter rod itself and the vacuum diaphragm that opens it are both functioning correctly, all of the vacuum lines are new and not leaking. Connecting vacuum directly to the diaphragm causes the shifter to immediately open. I've tried 3 different solenoids with the same result, all open when 12v is directly applied, but the manifold doesn't open at it's RPM point like it's supposed to. The solenoid sees a constant ~11v under all conditions, regardless of engine RPM. I've traced this wire back to the ECU and confirmed it's not damaged. No CEL other than for the SAI missing.
At this point, I'm assuming whatever circuit that controls this in the ECU is fried (cruise control doesn't work either.) I have an extra 24v vr6 (2.8) ECU sitting around which from what I've read uses the same hardware, just a different flash. This may be a stupid question, but if I were to take this to UM to get a performance flash, would I be able to basically overwrite the 2.8 ECU and make this work in the R? Would there be any issues with the immobilizer?
My husband has a 2011 GTI, which has just hit the 40k mileage mark. His CEL started coming on in March, but we figured it was due to him not tightening the gas cap enough, as he'd open and relock the gas cap, and the CEL would go away within a few restarts of the car. Took it into the stealership last week, got the 40k service (which was a bit of a rip-off in itself), and then got told the manifold was bad.
This is the exact text for the invoice: "Checked the vehicle for codes and found code P2015. Traced the intermittent failure to the intake manifold valve flap sensor failing."
I've seen a lot of posts around this problem, for many models and years, but it seems like most people managed to get it repaired under warranty / TSB. So I have three questions:
1. In the OBD codes, does it store date as well as code? In other words, is there a way to prove that this failed under 36k miles?
2. What's the process for getting this escalated to VWOA customer care, since I feel this should be taken care of under warranty?
3. The dealership we took the car to (which is not where we purchased the car, but is just closer to home) was shady, and the guy we worked with was, to say it nicely, a jerk.
Can oil leak out of Intake Manifold? i have Oil around lower intake manifold gasket. is this serious issue?
View 11 RepliesI have a chamfering noise coming from my intake manifold on idle. sometimes its there and sometimes its not, it goes away with any application of throttle.
View 9 RepliesI am just wondering at what revs the stock intake manifolds are meant to switch over as i think mine is stuck and not moving.
View 23 Replies2.4 Santa Fe ... I just took my Car to MOT inspection and found out there's a leak at my intake manifold and it's coming out of this place. it feels like brake fluid but my brake fluid is full?? I have seen many cars but never seen a part like this before. what is it doing there and why is it leaking ?
View 6 RepliesMy friend and I are working on her '03 1.8t and I noticed a huge oil leak under the intake manifold. It looks like there's a tube that has broken off and is now just spewing oil all over the place. I tried to get pics the best I could, so here they are....
I'd imagine its something that needs to be fixed asap.
